1'0 '1 whom it may concern.-

Be it known that T l surface of this ring 8 is provided with an an- Lunwio NEUMANN, a j nular groove 9, which coincides with a simisubject of the King 'il. Prussia, German Em" 3 lar groove in the respective disk 3 or 4 and peror, residing at Gxeiwitz, in the Kingdom 3 forms a race for the balls it}. of: Prussia and German Empire, have invented new and usel'ul lin n'ovolnents 111 Mechanism for Converting ltotatory ll liotion into Reciprocating Motion, of which tho 'lol lowing is a specification.

The present invention relates to improvements in that kind of mechanism for converting motion in which a reciprocating ring is mounted between two inclined rotary disks, and the object oi the invention is to adapt such mechanism for a greater variety of purposes, and quite particularly to enable it to be used for converting reciprocating into a rotary motion, which was not heretofore possible. Such mechanism comprises two curved or angular disks or the like arranged parallel to each other,- but inclined with regard to their axes of rotation and between which an annular part or ring is guided in such a man'- ner that during the rotary movement of the disks the said annular part is revolved and also caused to oscillate in the longitudinal direction of the axis. Mechanism of this kind is applicable to a great many purposes in the artas, for instance, for operating the slide-Valves of steam-engines and. of air, gas, and petrol motors as well as the pistons oi pumps and for many other purposes.

Figure 1 is a longitudinal sectional view of the improvement. Fig. 2 is a transverse sectional view of the same on the line 1 '1. Fig. 3 is a detail View oi" the rod. and link.

Fig. 4; is a side elevation, partly in section, of

another form of the improvement. Fig. 5 is an end view. Fig. 6 is a plan view, partly in. section, of the same; and Fig. 7 is a longitudinal sectional view of the in'iprovement cmbolying the modification shown in Figs; 4, 5, an 6.

Referring to Figs. 1, 2, and 3, disks 3 arid 4. are fixed to opposite ends of two shafts 2 and 1, arranged in alinement with dach other. The said disks are parallel to each other and at angles of approximately forty-five degreet. to the shafts 1 2. 'lhrough the centers of these disks passes a bolt 5, so that the shafts 1 and 2 are rigidly connected to each. other and the disks 3 and 4 are held at a certain distance apart. Between. the disks 3 i is arranged a ring 8, the thickness of which. corresponds a proximately to the distance between the (isks 3 and 4. Each. lateral By this arrsuigenient jarnn'iing and friction is avoided and it is rendered possible to considerably increase the stroke oi the mechanism. By unsure of one or more cranks the annular staid cranks are arranged in a 'ilane at ri ht an les to the revolvin t? In b :shajtts l and 2 and are fixed to' shafts or gudgoons 3i, which revolve in suitable bearings in the bipartite box To the shafts or gudgeons 3i lovers can be fixed outside the box. The 'to---and--h'o movement of the cranks 30 produced during the revolution of the shafts l 2 is transmitted to rods 33 by means of a (tormenting-link 33. (See Fi e. 1 and I3.) Said rods 33 can operate or e operated by pistons or the like. In the lat- 'ter case the reciprocating motion of the rods 33 is converted into the rotary motion of the shafts 1 and 2.

in order to increase or reduce the stroke of the oscillating part during the working of the mechanism or to stop the said stroke entirely, the arrangement shown in Figs. 4-, 5, and 6 can be used. in thiscase the disk 4, which is inclined at an angle of approximately forty-five degrees, is connected to the toothed segment 34, which. is provided with a dovetail guide in the part A worm 35 is in gear with the toothed segment 34, the said worm being integral with the bevel-wheel 36. V'Vith. this bevel wheel another bevel-wheel 37 is in gear, the latter being fixed to a shaft 38, which is rotatable within the shaft 1. If the slialt'IE Q rotated, the angle of inclination of the disk t with regard to the shaft 1 is altered. When this angle amounts to ninety degrees, no oscillation takes place; but the rotation oi the shaft 1 can still continue. With this arrangement the mechanism can also be used for controlling-gearfor in-- stance, in place oi link motion in locomotives. ill the toothed segment were made of su'ffioient length, the mechanism could also be used with advantage for the controlling-gearof engines which must be capable of reversing without stopping.

' it obvious that a ily wheel can be fixed to the driving-shaft in order to overcome the dead-points if the guiding-points are diametrically oppositc each other or it only one guidingpoint is provided on the ring 8. If,

are

however, there are several guiding-points on the circumference of the ring and these are l at angles of ninety degrees or one hundred and twenty degrees to each other, no deadpoints will exist, so that a fly-wheel is not necessary. The same also applies to the arrangement in which cranks are used.

v hat I claim, and desire to secure by Letters Patent, is-

1. hfiechanisn'iforconverting motion, comprising in combination two disks mounted at l an angle to their axes of rotation and parallel to each other, means connecting said disks with each other at the middle, an oscillating ring mounted between said disks, balls arranged between each side of said ring and I each of said disks, cranks pivoted at one end l to said oscillating ring, and a fixed frame to which the other ends of said cranks are piv- E oted, substantially as set iorth.

2. Mechanism for converting motion, com prising in combination two disks mounted at l an angle to their axes oi rotation and parallel to each other, n'icans connecting said disks with each other at the middle, an oscillating ring mounted between said disks, balls arranged between each side of said ring and each of said disks, cranks pivoted at one end to said oscillating ring, a frame to which the other ends of said cranks are pivoted, and means to alter the inclination of said disks, substantially as set forth.
